Title: Thread-forming devices and method for manufacturing same
IPC: B21H3/02
Filed: 1961-10-27
Abstract: 1,009,447. Making screws; self-tapping screws. RESEARCH ENGINEERING & MANUFACTURING Inc. Oct. 27, 1961, No. 38447/61. Headings B3A and B3N. A thread-forming member such as a selftapping screw is made by forming a blank of symmetrical arcuate polygonal cross-section of generally uniform width, and rolling a thread on the blank so that the radius of curvature of each side remains greater than the width of the cross-section. This results in a screw requiring a low driving torque but having a high resistance to thread stripping under load. Fig. 18 shows a cross-section of a screw similar to that in Fig. 1, the radii of the sides 102-104 and lobes 108-110 being shown, and also the difference 116 termed K between the pitch cylinder of the screw and that of the tapped hole. Formulµ expressing these radii in terms of K are given, defining the preferred range of dimensions. The blank may be five sided or have no lobes and the screw can be self-locking, Fig. 25, the pitch circles of the threads here forming a cylinder and the threads 57 being partly formed. Specification 957,675 is referred to.

Title: Method of manufacturing cellulose
IPC: F24H1/10
Filed: 1929-12-30
Abstract: 347,297. Cellulose. LA ROZA, J. J. DE, Tuinucu, Cuba. Dec. 30, 1929, No. 39776. [Class 96.] In a modification of the process described in Specification 322,763, [Class 96, Paper &c.], for the production of cellulose from annual plants such as canes, corn stalks, straws, and grasses, particularly applicable to the treatment of sugarcane fibre, the material, as free as possible from sugar, is shredded and screened to separate the short fibres and dust therefrom, and the long fibres impregnated with sulphurous acid and then stored for a suitable period, which may be several months. This treatment obviates the tendency to form fungi and other growths. After storing, the material is concentrated and then heated with sulphurous acid at a temperature not exceeding 110‹ C. A few minutes' heating yields a good quality cellulose pulp for paper making and three or more hours is required for the production of high content alpha cellulose such as is suitable for explosives, artificial silk, photographic films, pyroxylin products, cotton substitutes, absorbents, and the like. After washing and squeezing, the material is treated with alkali at a temperature below 100‹ C. For this treatment caustic soda or potash is preferred, but magnesia, lime, &c., sodium sulphate, sulphide, or sulphite may be used or added. Washing, followed by a more vigorous treatment with a similar alkali at a temperature not exceeding 160‹ C. for 4-6 hours, again washing and then bleaching, completes the process. The storing may be omitted and the acid treatment effected in one stage. The short fibres may be similarly treated.

Abstract: 1521545 Axial flow fans UNITED TECHNOLOGIES CORP 8 Oct 1975 [9 Oct 1974] 41224/75 Headings F1C and F1J [Also in Division F2]  A ring 60 is rotatable on the hub 26 of a ducted thrust fan to vary the pitch of fan blades 24 via horns 50 bearing parallel sided slots 52 which engage rollers 62 on the ring. The horns are oriented each relative to its respective blade so that they are all parallel to the hub axis 20 when the blades are in the feathered pitch position. To maintain contact between the horn slots and rollers 62 over the full range of pitch change operation, the horns may be slightly curved, alternatively the slots may be open at the top and the rollers of a length sufficient to prevent them from becoming disengaged. The axis of each roller 62 extends through the point of intersection of the blade axes 34 and hub axis 20. Rotation of ring 60 relative to hub 26 is effected by a harmonic drive 70 driven via a differential gear mechanism 72, gear 78, one way clutch 76 and input shaft 74 connected to a servomotor. The harmonic drive comprises a non circular wave generator 88 which forces a flexible gear 92 into engagement at two or more points with internal splines on a flange 42 connected to hub 26. Flange 42 and gear 92 which is connected to ring 60 have differing numbers of teeth so that rotation of wave generator 88 causes shifting of the flange 42 relative to gear 92 resulting in rotation of ring 60 relative to hub 26. The rotating hub carries with it planet gears 84, 98 of differential 72, the harmonic drive 70 and sleeves 86, 94, and 100, whilst the clutch 76, sleeve 80 and gear 104 into which gears 84 mesh remain stationary. When pitch change is required, gear 78 rotates sleeve 80, the rotation being transmitted via planet gears 84 to sleeve 86 and wave generator 88 causing rotation of ring 60 relative to hub 26.

Abstract: 1292400 Keyboards SCM CORP 28 Aug 1970 [28 Aug 1969] 41548/70 Heading G4H In a calculating machine information describing the location of the decimal point is fed into the storage register and displayed in it by synchronous depression of a value key and the clear key. The digit value representing the decimal point position is encoded in binary decimal code by encoder 18, and stored in register 54. The contents of register 54 is read serially into counter 36. Digits to the left of the decimal point are fed into shift register 20 in the position immediately to the left of the decimal point, and advanced to the left as successive digits are fed in. The exact timing of the operation is controlled by means of digit counter 38 and comparator 34, which compares the decimal point location with the current position of data in recirculating shift register 20. Digits to the right of the decimal point are fed directly into the correct position in the shift register. The digits are fed into the shift register 20 via gates 26-1 to 26-4, which are enabled by the output of comparator 34, and via register 22. The position of the decimal point on the display, which comprises multicathode tubes 88-1 to 88-8 is controlled in a similar manner by comparator 132. This comparator compares the decimal point location stored in register 54 with the value in digit counter 38. The digit value displayed is set by flip-flops 94 feeding a decoder which selects which cathode in the tubes is to be actuated. The particular tubes, i.e. digit position, to be actuated is set from the digit counter 38 via line 116 which activates the anodes of the tubes.
